Start with a Breakaway.
As if you were going to whip the string into the yo-yo, swing your
throwhand and bring the yo-yo into the air.

It is recommended that you
learn Yuuki's Slack Trick before attempting this trick. As you swing
the yo-yo up, pinch the yo-yo string with your non-throwhand relatively
close to the yo-yo and proceed to spin the yo-yo into the hanging string.
Continue around an extra rotation just as in Yuuki's Slack trick.

Again, just as in Yuuki's slack unmount the yo-yo
and swing back around, but this time you can allow it to completely swing
around to bring it back onto the string.

Again, this is similar to Yuuki's Slack Trick,
so pinch with your non-throwhand and spin around in the opposite rotation
from Step 2.
